    This update includes all PRs that have a needs-changelog tag:

    • Make static context const #1639
    • include: remove WARN_UNUSED_RESULT for functions always returning 1 #1659
    • cmake: Bump minimum required CMake version to 3.22 #1675 #1675
    • added: cmake: add a helper for linking into static libs #1678
    • doc: Promote “Building with CMake” to standard procedure #1680
    • also added cmake: Emulate Libtool’s behavior on FreeBSD #1685

    I had added the needs-changelog tag to #1685 because it seems noteworthy, but otherwise have not found any additional merged PR that would require a changelog entry.

    I’m not sure if the changelog entry for #1678 makes sense (CC theuni)

    13+#### Changed
14+ - The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` to the constant context object are now const.
15+ - Removed `SECP256K1_WARN_UNUSED_RESULT` attribute from several functions that always return 1. Compilers will no longer warn if the return value is unused.
16+ - The minimum required CMake version was increased to 3.22.
17+ - Building with CMake is no longer considered experimental.
18+ - Shared libraries built with CMake on FreeBSD now create the full versioned filename and symlink chain, matching the behavior of autotools builds.

    Pull Request Overview

    This PR updates the Unreleased section of the CHANGELOG to reflect recent merged PRs with the needs-changelog label, primarily around CMake improvements and context pointer constness.

    • Add a new CMake interface library entry
    • Mark static context pointers as const and remove now-unnecessary WARN_UNUSED_RESULT
    • Bump minimum CMake version, promote CMake builds, and align FreeBSD shared library naming

    CHANGELOG.md:14

    • [nitpick] The wording around pointer constness is a bit confusing. Consider clarifying that these symbols are now defined as const secp256k1_context* (e.g., “secp256k1_context_static and secp256k1_context_no_precomp are now of type const secp256k1_context*.” ).
    0 - The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` to the constant context object are now const.

    CHANGELOG.md:11

    • [nitpick] It may help readers if each changelog entry references the corresponding PR number (e.g., add (#1678) at the end) for easier cross-referencing.
    0 - CMake: Added `secp256k1_objs` interface library to allow parent projects to embed secp256k1 object files into their own static libraries.

    Entry for 1678 looks good to me.

26+The symbols `secp256k1_ec_privkey_negate`, `secp256k1_ec_privkey_tweak_add`, and `secp256k1_ec_privkey_tweak_mul` were removed.
27+The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` have been made const.

    0#### Added
1 - CMake: Added `secp256k1_objs` interface library to allow parent projects to embed libsecp256k1 object files into their own static libraries.
2 - build: Added `SECP256K1_NO_API_VISIBILITY_ATTRIBUTES` preprocessor flag (CMake option: `SECP256K1_ENABLE_API_VISIBILITY_ATTRIBUTES`) that disables explicit "visibility" attributes for API symbols. Defining this macro enables the user to control the visibility of the API symbols via `-fvisibility=<value>` when building libsecp256k1. (All non-API declarations will always have hidden visibility, even with `SECP256K1_ENABLE_API_VISIBILITY_ATTRIBUTES` defined.) For instance, `-fvisibility=hidden` can be useful even for the API symbols, e.g., when building a static libsecp256k1 which is linked into a shared library, and the latter should not re-export the libsecp256k1 API.
